I am using phpmyadmin to create a database, since my provider won't let me use telnet or my own MySQL client. I can't figure out how to do the ALTER commands as shown in Part 5 of the tutorial. After I have made a table, it seems I can only change/add rows, but not the columns of the table...

I confess I've never used PHPMyAdmin for any length of time, so I couldn't tell you for sure whether there is no way to alter an existing table's structure or there is such a feature that is just well hidden.

The alternative to using PHPMyAdmin is to write a simple SQL-processing page for yourself. The complete code for such a page is provided in "Professional PHP Programming" from Wrox Press, and is freely downloadable here. Download and unzip the file. Edit query.php and mysql_test.php (both in the "BOOKS\2963 Pro PHP\Full Code\Chapter 12" directory) to assign the appropriate values to $user and $password, then copy these two files to your Web server in a password-protected directory (as you did for PHPMyAdmin). Load query.php and type any SQL query you want, just like on the MySQL command line!

anyhow, click on your database, and you'll get a list of tables, with options like "insert" , "browser" .. there is also a "properties" .. click on that for the table you need to ALTER .. .then you have options to add fields and change fields.. that is what you are specifically looking for..
